For the placing of electrical engineering components in CAD the following shall apply:

I. Octant has positive x,y and z axis

Connection point at left, lower, back edge of bounding box

In most cases, it will be necessary to move the component in the direction of the X, Y and Z axes in order to achieve correct component placement.

You can implement translation and rotation using the Absolute plane [Fixed plane] dialog.

In the following example illustration, you can see a component with the correct alignment (Z pointing upwards), so that only one shift needs to be made (see entries under Point [Base point] ). As the Z-axis is pointing upwards, no axis rotations need to be made. The input fields under X-axis [X axis] retain the default values 1,0,0. The input fields under Y-axis [Y axis] retain the default values 0,1,0.

The point of origin [Base point] of the absolute plane is in the lower left, rear corner of the bounding box

The connection point can be set with angle [Angle] 0, as no rotation is to be carried out, or rotations are realized via the plane.

	Note
	The name of connection point can freely be chosen (in this example "CP_Orientation").

The coordinates of the connection point under "Position [Position] " can be left at 0.0 so that the connection point is at the point of origin [Base point] of the plane.

Set connection point

	Note
	Alternatively, a necessary shift can also be made here in the sketch instead of via the Absolute plane [Fixed plane] -> Point [Base point] dialog.

For components with incorrect orientation, make appropriate adjustments in the Absolute plane [Fixed plane] dialog under X-axis [X axis] and Y-axis [Y axis].

After the transformation (rotation + displacement) applies:

Example with rotation: The transformation happens with 2 rotations.

The original X-axis [X axis] is placed on the Z-axis (Z=1) and then the original Y-axis [Y axis] is placed on the X-axis (X=1).

Original coordinate cross and reoriented coordinate cross of the connection point

Result in E3

Model Properties - Correct orientation of axes and marked connection point

In an exported PS3 file you can check orientation and shift of connection point:

The connection point [Connection point] must now be classified.
